Once the add-on is installed, any time a user (or an admin) changes their e-mail address, details of the change will be logged in the Admin CP > Tools > Email Change Log page.

The main results page is a paginated list with the most recent log first. You can also filter by e-mail address. The add-on also keeps track of what the original e-mail address was (at the time the add-on was installed).

You can clear the log any time and delete individual entries.

HOW TO INSTALL
